A fuel cell is, in principle, a very simple electrochemical device. The chemical reaction that powers hydrogen fuel cells is the same as that which occurs when hydrogen burns. The chemical equation for this reaction is: 2H2 + O2 ( 2H2O + energy. "Normally hydrogen burns, reacting with oxygen from the air, producing water, heat and light. ... In the fuel cell the chemical reaction is exactly the same, but instead of producing light and heat energy, electrical energy is produced."2 All fuel cells consist of an electrolyte (a substance that allows only the passage of ions) sandwiched between two electrodes. When a fuel containing hydrogen is passed over the negative electrode, otherwise known as an anode, it is ionized. Ionization of the fuel, often accomplished with the assistance of a catalyst, removes electrons from the hydrogen creating positively charged hydrogen ions and negatively charged free electrons. Since only the ions can pass through the electrolyte situated between the electrodes, the electrons must find another route to the positive electrode or cathode, where they will be reunited with the hydrogen ions and combined with oxygen atoms to form water. The electrons passing around the electrolyte constitute an electric current, and thus can be used to provide power during their journey from anode to cathode.3

Negatively charged ions move to the positive electrode (anode) where they are oxidised meaning they lose electrons. This causes different elements to be formed at the different

A battery has three main parts: it has two terminals made of chemicals, which are called the anode and the cathode. There’s also the electrolyte, which detaches the two terminals. The electrolyte is a chemical medium. It allows the flow of electrical charge between the cathode and anode and when a device is connected to a battery the chemical on the anode releases electrons to the negative terminal. This is called an oxidation reaction. While this is happening, at the positive terminal the cathode accepts electrons. This completes the circuit for the flow of

Most of forest fires are caused by people. When doing their activities, they are often careless. For example, they do not put out a campfire or sometimes they drop a lighted cigarette. Sometimes forest fires are caused by arson, which is intentionally and illegally setting fire. Forest fires can also be started by natural factors, such as lighting, volcanic eruptions and sparks from falling rocks.

Nuclear fission starts off with an atom, the building blocks of matter. When an atom has an unstable nuclei, it is classified as a radioactive isotope. To further explain, a radioactive isotope are several atoms of the same element with different masses whose unstable nuclei splits and spontaneously releases radiation. In the process of

Nuclear fusion is a nuclear reaction where the atomic nuclei of low atomic number have been fused together to create a heavier nucleus with the release of energy. Fusion powers the sun which is already being conducted in laboratories throughout the world by scientists. Byproducts of the fusion process are a fast neutron and helium. These carry the heat to turn it into steam. Throughout the country there are 47 out of 50 states that support the fusion industry. For nuclear fusion to occur, there must be temperatures over a million degrees. On the sun and stars, nuclear fusion occurs. Hydrogen nuclei fuse to form helium nuclei in the sun. Only one percent of mass from an atom is converted into energy. It produces less radioactive weight

The electrical energy in the battery is converted from stored chemical energy. The electrical energy travels out of the battery and into the object

A battery generates electricity, or a current of electrons through a conductive path and there is a buildup of electrons through a chemical reaction in the battery. Batteries can be stored for a long time and still work because the chemical process doesn't start until the electrons flow from the negative to the positive terminals through a circuit. Volta discovered in 1800 that certain fluids would generate a continuous flow of electrical power when used as a conductor. This discovery led to the invention of the first voltaic cell, more commonly known as battery.

Battery generally has three main parts which are anode (-), cathode (+), and electrolyte. Each cell of a battery stores electrical energy as chemical energy in anode and cathode, and they are separated by an electrolyte which allows the flow of electrical charge between them (Goodenough & Park, 2013). Chemical reactions will occur on the electrodes when device is connected to battery and this creates a flow of electrical energy to the device.

What is nuclear fission? How does it work? What does it have to do with

small, positively-charged proton with a negatively-charged electron orbiting very fast, a model analogous to the earth orbiting the sun, or the moon orbiting the earth. Fuel cells take advantage of this structure. Using a membrane and a catalyst, hydrogen is broken up into a proton and an electron. While there are many different membrane models for fuel cells, the most appropriate one for car travel is the Polymer Electrolyte Membrane (PEM, also called the Proton Exchange Membrane). It is called this because protons are able to easily pass through the membrane. However, because the membrane does not allow electrons to pass through it, the electrons take a detour through an electrical circuit to the other side of the cell. If hydrogen is supplied into the cell at a steady rate, the stream of electrons in the electrical circuit creates electric power. However, like all batteries, you need a positive end (cathode) and a negative end (anode); in other words, the hydrogen atoms must have a “reason” to make this electrical circuit. And what is this reason? Oxygen. With oxygen at the other end, hydrogen is more than willing to create this current so that it can bind and form H2O, or water on the other end.

The world as we know today is dependent on energy. The options we have currently enable us to produce energy economically but at a cost to the environment. As fossil fuel source will be diminishing over time, other alternatives will be needed. An alternative that is presently utilized is nuclear energy. Nuclear energy is currently the most efficacious energy source. Every time the word ‘nuclear’ is mentioned, the first thought that people have is the devastating effects of nuclear energy. Granting it does come with its drawbacks; this form of energy emits far less pollution than conventional power plants. Even though certain disadvantages of nuclear energy are devastating, the advantages contain even greater rewards.
